Everyone feel free to jump in and say what is good, bad, odd, wrong, missed in the following.
NOTE WELL! Although it can be said for most aspects of this game, chasing BPs is an exercises in patience.
Select and focus on one target GB you want to acquire. Ask guildies, especially leadership, for advice and help acquiring target GB BPs.
I'm going to discuss two of the possible ways to get BPs. Aid and contributing to other player's GBs.
Aid: Expand your friends list with players of the age of the target GB preferably who already have the target GB. Check your guildies and hoodies for those with the GB. Instead of Aid, manually mo/po buildings of the Era of the target GB.
Contributing to other player's GBs: Remember that the goal is to acquire BPs! Getting FP and medal awards are nice, but not important at this point. Therefore aim for the lowest reward position that gives a Bp. (Exception, when you are chasing the last BP try for rewards that give multiple BPs, the chance of filling the last slot foes way up.)
Highlt recommended! Hold onto your Inventory FPs: there is no better general use for them then GB contributions, especially sniping.
Find those in Guild, Friend, Hood (in that order) who have the target GB. You will use two different methods, sniping and dominating.
Sniping: Every day review the target GBs in the Guild, Friends, Hood. Take any easy to acquire BP slots.
Dominating: Regularly contribute FPs to one target GB.
If you have at least one GB, the best way is to arrange a daily FP swap with the owner of the target GB. You will donate X FP to their GB, they will donate X FPs per day to your GB. Continue the daily swap until you have assured the reward you want, then stop contributing until the target GB levels.
if you do not yet have a GB, or the owner is not interested in sa swap, make regular FP contributions until you have assured the reward you want, then stop contributing until the target GB levels.
In either case, after you have assured the rewards you want, look for another player with a target GB to dominate.
Note well that dominating can turn to sniping!
Questions?
----------
Sniping Example. I am hunting Traz BPs. A guildie is in a dominating swap with another player. Because of the contributions from other players, the fifth reward slot costs 5 FP. I donate the 5 FP and wait for the GB to level and continue looking for other GBs to snipe.
Dominating Example: Same situation, but to grab 5th slot I need to donate 50 FP. My daily budget for BP acquisition is 10 FP. The owner doesn;t want to do a swap, so for the next 5 days I'll donate 10 FP per day to the Traz.
